Nick Boldt commented on JBIDE-21657:
------------------------------------

p2diff will simply show which features or plugins in a given project were changed by the PR. You could get the same information looking at the PR. Bear in mind too that each plugin will be shown as different because its Source-Reference in MANIFEST.MF will show a different SHA. 

So, a p2diff would in fact show that ALL the features and plugins were different since they'd have different versions in their qualifier. And if we exclude versions from the p2diff, you'd only ever see when a NEW feature/plugin is added or a new dependency is included in the update site.

As to not keeping these things forever... 

if I put everything into /snapshots/pulls/ then the automated cleanup scripts could be adjusted such that no more than 1 past pull request build would ever be retained, as we do currently for builds from the branch. Self-cleaning means you'd get to see your pull-request builds for a few days, but they'd disappear when they got sufficiently old.
